SCR APER.

Application filed. October 2', 1920. Serial nd. 414,173.

To all whom it may concern:

Be it known that I, Anette" Srnnnanxx, a citizen of the United States, residing at Vanderbilt. in the county of ()tsego and State of lvlichigan, have invented new and useful Improvements in Scrapers, of which the following is a specification.

This invention comprehends the provision of a scraper designed to be moved over the ground or surface for conveying material to some particular location, such asfor instance to a pit in the ground wherein buckets or the like from an elevator are filled.

an important object of the invention resides in the pro-vision of a novel construction f means for guiding the scraper in its movements.

The nature and advantages of the invention will be better understood when the following detail description is read in connec tion with the accompanying drawings, and wherein:

Figure l is a diagrammatic view showing the scraper in use.

Figure 2 is a perspective view of the scraper.

Figure 3 is a fragmentary transverse sectional view through one of the side members of the scraper and its associated part.

Figure 4 is a fragmentary view of the modified form.

Figure 5 is a perspective view of the chute used when loading a wagon with the scraper.

Referring to the drawings in detail, A indicates generally the scraper which is of substantially V-shaped formation in plan and which is composed of two vertically disposed members 10 and 11 respectively which are connected together by a top wall 12. Each of the side members is provided with a plate 13 secured to the inner side of the member and substantially coextensive in length therewith. The plate 13 depends be low the lower edge of said member and is formed with teeth 14 which. tend to break or clutch articles of hard format-ion upon light er soil as the scraper is drawn over the ground. The scraper is arranged upon the ground or surface in a manner as stated in Figure 1, and is moved over the ground through the instrumentality of a cable 15. This cable is connected. to the apex of the scraper as at 16 and is trained over a pulley 17 positioned on the ground at some fixed point, between which and the pit 18 the scraper operates. The cable is connected to a motor operated drum or the like (not shown). 'Itis of course understood that the plates 13 are being removahly associated with the side members 10 and ll of the scraper and canbe detached and shoes with a smooth surface used when desired. Straddling the scraper in its entirety is a substantially U-shaped' member 18 constituting a fixed support, the seat for the center being indicated at 19.

Pivoted upon the U-shaped member 18 at the opposite sides of the scraper, are levers at 20 each of which is equipped. with a look ing element 21 which co-operates with a rack bar or segment at 22 for holding the lever fixed in any given position. These levers are disposed within convenient reach of the occupant of the seat 19, Each lever is equipped at its lower end with a shoe or the like 23. As either lever is manipulated it brings the shoe in contact with the ground or surface, thereby raising the adjacent side of the scraper away from the ground leaving the other side in contact therewith and which will cause the scraper to be moved to one side or the other depending upon the particular lever which is operated. As above stated the lever is held in its adjusted position through the instrumentality of the locking element and associated with the tooth segments of the rack bar. In contra-distinction to the shoe 22 the levers may be equipped with a ground engaging wheel of any suitable character such as shown in the modification illustrated in Figure 4, wherein the lovers are indicated at 25 and the wheels at 26. In practice, the scraper is moved over the ground or surface in a direction of the pit 14' being properly guided in its movements in a manner just described, and conveying the material into the pit 14L "from which it is taken by the buckets of an clevator indicated generally at B.

in F' we :3 shown a block 27 having an inclv surface at 28 upon which the aper can be moved in an upward direction for conveying the material. into a wagon or the like in contra-distinction to conveying the material into the pit 14. The block Ina be of any suitable dimensions and constructed from any suitable material.

While it is believed that from the time going description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be re hat I claim is: y A V A scraper of the character described coinprising a substantially V-shaped member in plan, said member including a top and sides, plates secured to the sides and substantially coextensive in length therewith, said plates projecting below the lower edges of the sides and provided with teeth, an inverted U shaped bracket straddling the member and secured to the sides thereof a seat supported on the cross piece of said bracket, toothed segments supported by the parallel portions of said bracket at the sides of said member, levers hivoted on the parallel portions of the bracket, ground engaging members carried by the corresponding lower extremities of said levers, and pawls associated With said levers and co-operating with said toothed segments as and for the purpose specified. e

In testimony whereof I afiix my signature.

AUGUST SPREEMAN.
